She, a senior forensic doctor, used her extraordinary insight to dig out the irrefutable evidence from under the skin: this was not an accident, but a long-planned murder!

Step by step, she suddenly discovered that the identity of the deceased was shockingly related to her own life experience - he might be her biological father!

In cooperation with the criminal police captain Zhou Yiran, who is both an enemy and a friend, Su Qinghe must race against time, struggle in the whirlpool of the truth and life experience, use silent testimony to tear apart the corrupt shady curtain, avenge his father, and clear his name!
